[Q] Unable to tether after Ad-Hoc fix - Xoom Q&A, Help & Troubleshooting

I am unfortunately unable to post a reply within the original thread with this fix as it is in the Development forum. So here it is..
I have applied the wpa_supplicant fix from this thread:

I can now see Ad-hoc networks but when trying to connect to it I am stuck at Obtaining IP Address.
Connecting to Infrastructure networks works fine. Other devices can connect to my Ad-Hoc network. But the Xoom will not obtain an IP Address.
I have tried setting static IP and using open DNS options such as Google's DNS servers but that doesn't work either.
I am using a canadian wi-fi only xoom. I have updated to the most recent US Xoom, Wi-Fi only firmware from Motorola and used this method for the root and unlock:

I am trying to tether to a Samsung i5700 that is rooted using WiFi Tether or Barnacle. Both do the same thing.
I've also tried bluetooth tethering but the two devices will pair but not connect.

Mine does that too where it will hang on Obtaining IP address just make sure your phone is on meaning the screen is on (showing wifi tether.) For some reason it can run but not connect very well while the screen is off. Don't know why this is, but it's been only a minor inconvenience.

Even with the phone screen on, showing the wifi tether screen it doesn't connect. And when I assign a static IP address Wifi Tether never notifies that a client has connected.

[Q] [openvpn, cm7] Hotspot not functional when openvpn is connected

I'm using CM7 stable (7.0.3) with a Nexus One.
When I enable the hotspot feature without having the phone connected to my openvpn server, my laptop (connected to the hotspot) connects to the web fine. The phone's internet connection works fine as well.
But when I enable the feature while connected to the openvpn server, even though the internet works on the phone, my laptop connects to the hotspot but cannot send/receive any data. I can ping my phone from my laptop, but pings go unanswered for example to google.com or 8.8.8.8...
Does anyone have any idea what's going on here, how I can troubleshoot or how I can fix the problem?
PS. I'd like to have the phone connected to my openvpn server rather than my laptop while using the hotspot as the laptop's openvpn connection is unstable when using the phone's hotspot (I do't know why).
Thanks!
I think the problem is the Gateway used by the laptop to connect to the internet. When you activate the hotspot the laptop will use to connect to the internet as gateway the ip provided by 3G. When you activate the VPN the gateway is changed but the laptop can't tell that and it uses the wrong IP address.

[Q] Wifi Tether and DDWRT for a complete home network

OK, my wife and I each have Sprint Samsung Galaxy S3's. We both have Wifi Tether TrevE mod installed and working and we also have a linksys router running DD-WRT.
I have wanted for a long time to create a stable home network with the router using our phones for internet. Reason being, We both have laptops that need access to our WiFi networked printer. And I also wanted to create a networked storage.
I started out trying to use the Router as a repeater bridge. The problem here is that in that mode there is no DHCP server in the router, so when you turn off WiFi Tether in the phone, there is no IP assignment taking place since it is handled by the phone. This is ok for the printer because we can set a static IP, but not ok for the laptops because they need to have auto ip assignment for all the other networks they might encounter. Plus I'd like to be able to have a friend come over and use the printer if need be without having to change his IP address. So this setup is unstable.
Then I tried the Router in Repeater mode. In this mode IP addresses are being assigned and everyone can see everyone else on the network. The problem here though, is that the Router and all connecting devices have to be in a separate subnet than the WiFi Tethering phone, i.e, Tethered Phone on 192.168.1.x and Router on 192.168.2.x (as far as I can tell anyway, I've tried putting them on the same subnet but fail to get internet access.) It's a problem because I have Samba Filesharing installed on the phones and the tethered phone is in a different subnet and not visible on the network. I want all devices visible.
So that's kind of where I am now, Wifi Tether on both phones (each setup with same settings so either phone can be used as our internet gateway) but they are on a separate subnet from the rest of the network while tethering.
How do I get all of my devices to be visible on the network?
Do I need a different setup in DD-WRT?
Currently it is setup in Gateway mode with DHCP server and wireless is in repeater mode with a VLAN setup with a different SSID from the WiFi tethered phone.
Do I need to usb tether the phone to the router? I have a usb port on the router but I've not found good instructions for getting the phones internet through to the router that way and I'm not sure that I would want it that way since I wouldn't be able to walk around with my phone.
Is there a way to make devices in different subnets visible to each other? Some kind of bridging or static routing or something?
Is it possible to have the phone connect to the router in a normal manner and for the router to then share the phones internet connection with the rest of the network? Then at least the router could run DHCP and be stable even without the phones.
Again, just to clarify, I want a home network with devices connecting to my WiFi router running DD-WRT and internet being provided by one of our phones, but with the network remaining intact when the internet provided phone is removed. Thanks for your help.
Bonus questions:
Is it possible to harness the power of both of our phones internet connections into one network by any means possible?
Are there any other wifi/tethering apps or another version of WiFi Tether that offer more features or the functionality of DD-WRT?
did you see this?

Thanks. Not much new there other than Barnacle. Didn't know about it, tried it, doesn't work on my phone. I would like to see a version of WiFi Tether with some more options though, why couldn't we have one with the same options as DD-WRT?
I did some more reading and I think what I need to do is link the subnet created by the router to the primary router (the phone serving Wifi Tether) through static routing. Unfortunately the static route needs to be done through the primary router and WiFi Tether doesn't include features like that.
I'll do some more experimenting and see what happens.
[A] Cellular Phone/USB Modem As WAN Connection
Answer is in the DD-WRT Wiki, here (http://www.dd-wrt.com/wiki/index.php/Cellular_Phone/USB_Modem_as_WAN_connection).
Or just google "DD-WRT Cellular Phone/USB Modem As WAN Connection", it should be the #1 result.
Their WIKI is a great resource.
Good luck!
EDIT:
In retrospect, I am unsure about linking to the DD-WRT site... external and all. If this is a no-no just let me know and I will delete the link.
DD-WRT Client Bridge worked for me
I was able to do what you're trying to do by configuring my DD-WRT router as a Client Bridge.
I can't post the link, but there are directions I followed exactly on the DD-WRT wiki in the section:
DD-WRT wiki mainpage / Linking Routers / Client Bridged
I'm connecting my router to the tether via wifi, and connecting my wired devices to the router. I haven't had it working long, but so far it has been great.
Got it, sort of
Just to update this thread. The client bridge is a great way to connect a wired network to the bridge but loses out on creating a stable wi-fi network when the phone tether is turned off.
Anyway, the final setup I managed was having the DD-WRT router set as a wireless repeater with a computer connected to it running a DHCP server. The computer takes care of the IP addreses so that we have a stable wired/wi-fi intranet when the phone is not sharing it's internet connection.
Update: I founde another solution/project based on OpenWRT
http://ofmodemsandmen.com/
my exploits using a Linksys E3000 have been documented here:
http://tweakedrom.com/forum/viewtopic.php?f=6&t=7
I kind of like the USB tether thing. The E3000 Router USB power charges and maintains my SCH-i605 (Verizon Samsung GN2) running CM12.1. I use this as a backup connection or in the event of main cable modem service disruption at the house. It is also great for traveling (hotels) or camping (car 12v adapter for router, or power inverter)
I just bought a used Asus RT-N66U router. Out of the box it supports USB tethering with android phones and dual WANs for failover/load balancing. ROOter also works, tested the x86 build on an old PC. I'm looking to cut out my ISP completely and just use 4G from the phone for internet. The issue I have run into is that I can't appear to do DDNS or port forwarding. My wireless carrier (verizon) appears to be employing a double NAT. If I perform a speedtest on the ookla app, I get 2 IP addresses in the results, an "internal" and an "external". Both are in the public range but I can't DDNS in with either of the IPs, nor can I get any kind of service working.
Anyone have a solution for this? I'm not 100% sure but I wonder if using the SIM card in a dedicated USB 4G modem (not tethering via the phone) would get me a direct IP? I suppose I could also sign up for a VPN service and run OpenVPN on the router but that'd cut down on speeds I think. I've also heard about punching holes for ports but I'm not 100% sure how that works, I assume I still need some 3rd party public IP for relaying or something.

Can't connect to wifi network (WPA PSK)

So, after browsing a bit about this I'm still unable to connect to my work wifi network. Every other network I'm able to connect just fine.
I put the wifi password, authenticates, goes to "obtaining ip address", goes back to authenticate.. and doesn't connect.
Forcing (using manual IP configuration) connects but doesn't open websites, even tho I'm using the connect gateway / dns servers. (even used 1st dns same as gateway).
Got a LG 4x next to me connecting just fine, problem is only on my nexus 5.
So far happens on 4.4.2 and 4.4.3.
Tried some tips that I saw around the web like disabing nfc or turning on and off airplane mode (although there isn't much logic in these), but still nothing.
Wifi password is correct.
Problem it seems is somewhere obtaining the ip from the router or something, as it goes back when it reaches this point, but then again forcing it allows me to connect but doesn't open websites.
Any tips? I'm suing WPA2 PSK at home and it's fine.
The network is in a 2ghz range channel 10.
Any help is appreciated.
PS - Router is a linksys WAP54G.
Thanks a lot!

[Q] Can't connect to Open WiFi hotspots

Hi All,
I have to OTA KitKat 4.4.4. running on my Nexus 5 and I can't connect to any Open WiFi hotspots.
That is ones that do not have any security set.
I have even not been able to connect to Netgear DGN1000 with it's OOTB settings of SSID: NETGEAR and no security.
Any thoughts...
Are you getting an error message? Do these open networks perhaps have MAC ID filtering?

No error message, and MAC filtering should not be on where I first tried as it was a public wifi hotspot.
I have since removed all stored profiles and then re-booted, as per instructions elsewhere. Since then I can connect to the guest network on my dd-wrt powered router, so I think that have helped.
Not been near a public wifi hotspot since, will report back when I do.

Bluetooth tethering to other android phone - no internet

Hi guys!
I have an issue with bluetooth tethering between two android phones:
A-Oneplus One cm12.1 latest nightly
B-Xperia SP cm11 latest stable release
Bluetooth tethering is activated on A, and paired up with B. Then I activate the "use internet access" option on the bluetooth pairing settings. Then when I try to access the internet on B, I get a "could not find server" error. It is not a dns issue as the problem is the same when using ip addresses.
I tried to isolate the faulty phone with two scenarios:
I connected a friend's phone running kitkat to A: internet worked fine, which led me thinking that A was sharing its connection correctly and thus B was at fault. But then I connected B to my friend's phone in bluetooth tethering mode: internet worked fine, so B can receive bluetooth tethering internet correctly...
Could it be that lollipop phones have trouble sharing bluetooth internet to kitkat phones? Seems a bit fishy to me...
Is there a command line tool (like pand on old cyanogen phones) to manually configure A or B?
Any ideas? Thank you!
Update:
I ran a netfcg on B: it showed that bt-pan didnt have any Ip address assigned.
So i did
netcfg bt-pan dhcp
ip route add default via 192.168.44.1 (A's ip address).
Now i can ping any internet IP, but I cannot ping web addresses. How do I set the correct dns in this case?
Thanks!
This post solved my problem.
